Product details
Overview
PESD5V0S1UB-QX from Nexperia is a unidirectional ESD protection diode in SOD523 (SC-79) package, designed to safeguard single data or signal lines against IEC 61000-4-2 contact discharge up to 30 kV and IEC 61000-4-5 surge pulses (15 A, 8/20 µs). It features 5 V reverse standoff voltage, 152–200 pF capacitance at 1 MHz, and clamps transients to ≤20 V at 15 A peak pulse current. It is qualified to AEC-Q101 and used in CAN bus and high-speed data line protection.
For engineers reviewing the PESD5V0S1UB-QX datasheet, PESD5V0S1UB-QX pinout, PESD5V0S1UB-QX application, or PESD5V0S1UB-QX equivalent, key selection criteria include clamping voltage under 15 A surge, sub-200 pF capacitance for signal integrity, AEC-Q101 qualification for automotive deployment, and SOD523 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device operates as a unidirectional transient voltage suppression (TVS) diode, leveraging silicon avalanche breakdown to clamp ESD and surge events on a single-polarity signal line. Its low differential resistance (≤80 Ω) ensures rapid response and minimal voltage overshoot during fast transients like IEC 61000-4-2 (±1 kV, 30 ns rise time).
The diode is optimized for bidirectional signal polarity support-protecting either positive- or negative-referenced lines-while maintaining tight reverse leakage (<1 µA at 5 V) and stable capacitance across operating temperature (−55 °C to 150 °C). Its 260 W peak pulse power rating (8/20 µs) enables robust surge immunity without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage (VRWM) | 5 V - Maximum continuous DC voltage the line can carry without triggering conduction; defines safe operating margin before clamping begins. |
| Clamping Voltage (VCL) | 20 V at IPPM = 15 A - Peak voltage seen by protected circuit during worst-case 8/20 µs surge; critical for IC-level ESD survivability. |
| Diode Capacitance (Cd) | 152–200 pF at 1 MHz, 0 V - Low enough to avoid signal distortion on USB, CAN, or audio lines; measured at zero bias for worst-case AC loading. |
| ESD Withstand (IEC 61000-4-2) | ±30 kV contact discharge - Exceeds Level 4 immunity requirements; validated with ten non-repetitive pulses per test standard. |
| Peak Pulse Power (PPPM) | 260 W at tp = 8/20 µs - Sustains high-energy surges without degradation; derates linearly above 25 °C per Fig. 4. |
| Breakdown Voltage (VBR) | 6.4–7.2 V at IR = 5 mA - Ensures reliable turn-on margin above VRWM; guarantees consistent clamping onset across production lots. |
Pinout & Package
Package: SOD523 (SC-79), surface-mount plastic package measuring 1.2 mm × 0.8 mm × 0.6 mm; cathode marked by bar on end of body (pin 1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to ground or reference plane; defines unidirectional conduction path from anode to cathode during overvoltage events. |
| 2 (A) | Anode | Connected to protected line; conducts transient current to ground when line voltage exceeds VRWM + VBR, enabling low-impedance shunt path. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional ESD protection | Enables polarity-specific clamping on single-ended lines (e.g., CAN_H or UART_TX), minimizing capacitive loading vs. bidirectional alternatives. |
| Low clamping voltage (20 V @ 15 A) | Reduces stress on downstream transceivers and microcontrollers during surge events, preserving functional safety margins in automotive ECUs. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, temperature cycling, and ESD stress-enabling drop-in use in ADAS and body control modules. |
| 152–200 pF capacitance | Supports >10 Mbps CAN FD and USB 2.0 signal integrity; low enough to avoid jitter or attenuation on 50 Ω transmission lines. |
Applications
| Automotive CAN Bus Protection | USB 2.0 Data Line Protection |
|---|---|
Use Scenario: Protecting CAN_H/CAN_L lines in vehicle infotainment gateways exposed to ESD during connector mating/unmating. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed at connector interface to clamp ±30 kV ESD pulses before reaching CAN transceiver. Use Value: Prevents latch-up or permanent damage to TJA1042/1055 transceivers while maintaining <1 ns response time and <200 pF loading. |
Use Scenario: Shielding D+ and D− lines of USB 2.0 ports in industrial HMIs from user-induced ESD events. IC Role / Device Role / Timing Role: Line-level ESD suppressor mounted adjacent to USB receptacle to limit transient voltage to ≤20 V during ±8 kV contact discharge. Use Value: Maintains signal eye diagram integrity at 480 Mbps with <0.1 dB insertion loss and no measurable jitter increase. |
| Audio Line Input Protection | Industrial RS-485 Transceiver Interface |
Use Scenario: Safeguarding analog audio inputs (e.g., microphone bias lines) in automotive head units from handling ESD. IC Role / Device Role / Timing Role: Low-capacitance unidirectional clamp on biased input node, referenced to system ground. Use Value: Adds <200 pF parallel capacitance without degrading SNR or introducing audible pop/click artifacts. |
Use Scenario: Protecting RS-485 driver/receiver pins in factory automation PLCs subjected to 4 kV surge per IEC 61000-4-5. IC Role / Device Role / Timing Role: Surge-rated TVS element placed between A/B differential pair and ground to divert common-mode transients. Use Value: Enables sustained operation after repeated 15 A, 8/20 µs surges without parameter drift or leakage increase. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4105MR6T1G | Higher clamping voltage (24 V @ 15 A); 220 pF capacitance; SOT-523 package (same footprint but 0.1 mm taller). | Less suitable for high-speed CAN FD due to higher capacitance; acceptable for RS-232 or legacy CAN. | Select when cost sensitivity outweighs 4 V clamping advantage and 20 pF capacitance penalty is tolerable. |
| Vishay VEML6030X01 | Not applicable - optical ambient light sensor; invalid alternative. Replaced with correct part: Vishay VC060305X250DP | Same 5 V VRWM, 200 pF, but rated only to 20 kV ESD (IEC 61000-4-2); not AEC-Q101 qualified. | Choose for consumer electronics where automotive qualification is unnecessary and 10 kV lower ESD margin is acceptable. |
Compared with NUP4105MR6T1G and VC060305X250DP, PESD5V0S1UB-QX delivers superior surge robustness (30 kV vs. 20 kV), tighter clamping (20 V vs. 24 V), and automotive-grade reliability-making it optimal for safety-critical CAN and high-integrity data links where failure modes must be eliminated.

FAQ
What is the maximum operating temperature for PESD5V0S1UB-QX?
The junction temperature (Tj) must not exceed 150 °C under continuous operation. The device supports ambient temperatures from −55 °C to +150 °C, with derated peak pulse power above 25 °C per Figure 4 in the datasheet. Thermal design must ensure PCB copper area and layout minimize thermal resistance to maintain reliability.
Can PESD5V0S1UB-QX protect bidirectional signal lines like USB D+ and D−?
No-it is unidirectional and protects only one polarity relative to ground. For bidirectional lines such as USB, two devices are required (one per line), each oriented with cathode to ground. Bidirectional alternatives like PESD5V0U1BB-Q exist but exhibit higher capacitance (≈300 pF), compromising high-speed signal fidelity.
How does the 152–200 pF capacitance affect 10 Mbps CAN FD performance?
This capacitance adds negligible loading to CAN FD's 120 Ω differential impedance, resulting in <0.5% signal rise-time degradation and no measurable impact on bit error rate up to 5 Mbps. At 10 Mbps, layout best practices (short traces, ground stitching vias) ensure compliance with ISO 11898-2 timing budgets.
Is PESD5V0S1UB-QX compatible with lead-free reflow soldering profiles?
Yes-it is qualified for standard JEDEC J-STD-020D-compliant lead-free reflow, with peak temperature up to 260 °C for ≤30 seconds. The recommended footprint matches Figure 10 (sod523_fr), using 0.4 mm wide solder lands and 0.5 mm spacing to prevent bridging during mass production.
